Thanks a lot! Thanks to your help, i managed to unlock my T470s. Although i know about the very useful help section, here some notes for others who might want to try the method as well (sorry for redundancy to other comments and instructions):
* the whole process is perfectly described here: [url]https://www.youtube.com/watch?v=1ypCYSxbxyY[/url]
* i used a 9$ CH314a programmer with the 3V fix (see [url]https://www.youtube.com/watch?v=HwnzzF645hA[/url])
* in-circuit flashing didn't work for me, so unsoldering seems to be mandatory for T470s
* i found that i needed to erase...

Hi,
i found this forum while searching for info on how to handle a locked Lenovo BIOS.
It's nice to see so much more info in the forum. And at thia point I'm really wondering why i haven't heard of badcaps forum before.
Cheers!
